This 400W air cooled spindle is ideal for small CNC routers, engravers, and hobby machine builds, offering quiet operation and smooth cutting performance. Its round body makes it easy to mount using standard spindle clamps, and the ER11 collet system allows a range of small tool sizes to be used for engraving and light milling.

Spindle speed is controlled by adjusting the input voltage, making it easy to match cutting speed to material. Suitable for wood, plastics, PCB machining, and lightweight CNC routing applications.
